hey guys! well, after our first checkpoint, we sat down and really started getting into the details of the design, especially the software. After getting the two Xbee modules to communicate with each other, we realized that our code would need to be interrupt driven to successfully read, process, and send messages on time. We're allowing one module to handle the interface with the Xbee, saving us some complexity of having to check flags and all that. Check out our design to the right. ignore the doodles to the right.
